Sagot :
Answer:
x =83
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two opposite interior angles.
x+43 = 126
Subtract 43 from each side
x = 126 -43
x =83
Let's take this problem step by step:
For the angle adjacent to the exterior angle of 126°:
⇒ exterior angle plus the that angle is equal to 180 degrees
⇒ since it is on a straight line
[tex]126 + that_.angle=180\\\rm \hookrightarrow that.angle=180-126\\\rm \hookrightarrow that.angle=54[/tex]
The sum of all the angles in a triangle is: 180°
[tex]that.angle+43+x=180\\\rm \hookrightarrow 54+43+x=180\\\rm \hookrightarrow 97+x=180\\\rm \hookrightarrowx=83[/tex]
The size of angle x is 83°
Answer: 83°
Hope that helps!
